这个错误通常是由于访问了超出vector边界的索引而导致的。在上面的代码中,创建了一个长度为5的vector字符串数组,但没有给每个元素赋值。这导致在访问vector时出现了错误。
要解决这个问题,你可以通过以下两种方式之一来修复代码:
1. 在创建vector时,为每个元素赋初值:
```c++
#include <vector>
#include <string>
int main() {
std::vector<std::string> myStrings(5, ""); // 给每个元素赋空字符串初值
return 0;
}
```
2. 使用`push_back()`函数向vector中添加元素:
```c++
#include <vector>
#include <string>
int main() {
std::vector<std::string> myStrings;
myStrings.push_back(""); // 添加一个空字符串元素
// 添加更多元素...
return 0;
}
```
这样就可以避免访问超出vector边界的错误。
